Large Fruited ElmUlmus macrocarpa

Water regularly, especially during dry periods, to maintain consistent soil moisture. Allow the top few centimeters of soil to dry out between waterings.

Reduce watering in winter when the plant is dormant to prevent waterlogged roots. Ensure good drainage to avoid root rot.

Prune to shape the tree, remove dead, damaged, or crossing branches, and to improve air circulation. The best time for major pruning is late winter or early spring before bud break. Light shaping can be done in summer.

Aim for a strong central leader and well-spaced branches.

Propagation is typically done by seed, which requires a period of cold stratification. Cuttings can also be taken from semi-hardwood or hardwood, usually in late summer or fall.

Successful propagation depends on maintaining appropriate moisture and temperature conditions.

Young trees benefit from repotting every 2-3 years, while mature trees require it less frequently, perhaps every 5-7 years. Repot in early spring just before new growth begins.

Trim some of the root system to encourage new root development and ensure the plant is not root-bound.
